Just to be nice.
The Lamborghini Gallardo Spyder can cost hundreds of thousands of dollars, and it accelerates way faster than the street requires. Roady's video shows him turning this powerful vehicle into a brief escape for some grateful passengers. According to his YouTube description, at least a few of the riders are homeless people he picked up in Santa Monica, California.
RightThisMinute notes that while Roady isn't giving out material items, he is providing some needed fun. "This is a great way to start my day," one rider says in the clip.
Incidentally, Roady, aka Dr. Deeds, can also be seen on the Web performing all manner of kind acts -- with a lot less horsepower.
